Why did Arthur Andersen’s auditing and consulting work for Enron raise concerns about independence?

Arthur Andersen’s dual role as both auditor and consultant for Enron created a significant conflict of interest that compromised its independence. During the 1990s, the firm shifted its focus from traditional auditing to generating high-profit consulting fees, leading to a business model where growth relied heavily on these lucrative services rather than standardized audits.1

This dependence on consulting revenue incentivized Andersen to prioritize client satisfaction over objective oversight. Specifically, the Houston office billed Enron $1 million per week for combined auditing and consulting services. This financial entanglement fostered an environment where:1

• Performance Pressures: Lead auditors were driven by aggressive sales goals, such as a 20% annual increase in revenue, which discouraged rigorous scrutiny of a major client.1
• Lack of Professional Distance: The lead auditor, David Duncan, had personal and professional ties to Enron’s chief accounting officer, which undermined the necessary detachment required for an independent audit.1
• Client Intimidation: The firm’s reliance on Enron’s business allowed the client to exert pressure on auditors, including instances where Andersen staff were intimidated into approving questionable financial decisions.1

These failures ultimately prompted the passage of the Sarbanes-Oxley Act of 2002, which prohibited audit firms from performing certain unrelated consulting services for their clients to ensure future auditor independence.2
